To assess the role of magnesium sulphate infusion after coronary artery bypass graft (CABG) surgery in  preventing atrial arrhythmias that may occur following CABG operation. Cardiac anaesthesia wing of   Bangabandhu Sheik Mujib Medical University, Dhaka from 2007 to 2009. Design: Prospective randomized  non blined. All patients under going primary CABG surgery and having sinus rhythm before surgery were alternatively randomized into the study or control group. Patient with history of Atrial Fibrillation (AF), Left   Atrial (LA) dysfunction, renal-impairment and implanted pace maker were excluded from the study. The patients in the study group received 10 mmol of magnesium (2.47gm) in 10 ml saline intravenously over 10 min after termination of Cardio Pulmonary Bypass (CPB). The end point was development 0f AF for 10 min   or if an episode of AF had to be treated because of symptoms. A total of 60 patients were included in the study 30 in each group. The incident of AF was 14% in patients who received single dose of magnesium. The  patients without magnesium had an AF incidence of 20% (p=0.353) not significant. Single dose magnesium infusion does not prevent AF statistically, but the haemodynamic parameters in patients receiving magnesium were more stable during the whole period of observation.

This chapter is focused on the analysis and classification of arrhythmias. An arrhythmia is any cardiac pace that is not the typical sinusoidal one due to alterations in the formation and/or transportation of the impulses. In pathological conditions, the depolarization process can be initiated outside the sinoatrial (SA) node and several kinds of extra-systolic or ectopic beatings can appear. Besides, electrical impulses can be blocked, accelerated, deviated by alternate trajectories and can change its origin from one heart beat to the other, thus originating several types of blockings and anomalous connections. In both situations, changes in the signal morphology or in the duration of its waves and intervals can be produced on the ECG, as well as a lack of one of the waves. This work is focused on the development of intelligent classifiers in the area of biomedicine, focusing on the problem of diagnosing cardiac diseases based on the electrocardiogram (ECG), or more precisely on the differentiation of the types of atrial fibrillations. First of all we will study the ECG, and the treatment of the ECG in order to work with it, with this specific pathology. In order to achieve this we will study different ways of elimination, in the best possible way, of any activity that is not caused by the auriculars. We will study and imitate the ECG treatment methodologies and the characteristics extracted from the electrocardiograms that were used by the researchers that obtained the best results in the Physionet Challenge, where the classification of ECG recordings according to the type of Atrial Fibrillation (AF) that they showed, was realised. We will extract a great amount of characteristics, partly those used by these researchers and additional characteristics that we consider to be important for the distinction mentioned before. A new method based on evolutionary algorithms will be used to realise a selection of the most relevant characteristics and to obtain a classifier that will be capable of distinguishing the different types of this pathology.

Atrioventricular node ablation (AVNA) combined with His bundle pacing (HBP) are feasible, safe, and effective in patients with refractory atrial fibrillation (AF), however, the pacing parameters of sensing and capture threshold maybe sometimes unsatisfactory. Left bundle branch pacing (LBBP) provides obvious advantage in patients with conduction diseases at the distal His bundle for its better sensing, a lower and more stable capture threshold. Among hypertrophic cardiomyopathy (HCM) patients, AF is a common sustained arrhythmia, primarily caused by left atrial dilatation and remodeling. Few is known about the feasibility of electrophysiological performance, safety and clinical effectiveness of atrioventricular junction ablation (AVJA) combined with LBBP in patient with refractory AF and HCM. Here, we report a case of a 56-year-old woman suffering from refractory AF and HCM, however HBP was failed for its unsatisfactory sensing, a high and unstable capture threshold for her, therefore, ablation and LBBB were accepted by her to achieve better rate control. Improvement in symptoms, quality of life, and exercise capacity has been observed during the 1.5-year follow-up. To our knowledge, our case originally confirmed that the combination of AVJA and LBBP, without the defect of AVNA combined with HBP, is a better strategy with feasibility and safety for refractory AF patients with comorbidity of HCM, additionally, it may make LBBP more applicable and valuable among patients suffering from HCM meanwhile pace maker treatments are essential.
